I get pretty terrible battery life on this ROM. I was used to getting at least 13 hours on CM10 but now I'm getting like 10. Anything I can do? The phone actually seems to go into deep sleep and have less time awake on 10.1 compared to 10, but it chews through battery.

I usually don't like to keep cm10 as my daily driver but cm10.1 has been surprisingly well. Try using tasker to toggle 2g when Wi-Fi connected and LTE when disconnected. I was on Wi-Fi all day and got 50 percent juice left with over 2.5 hours of screen on. I also adjust auto brightness settings since the stock values seemed really high.

On another note, will nfc while screen off be implemented on this rom like the viperrom? I really liked that feature but I can't seem to be able to find any threads about it on our device...
